A Possible Path to Polypeptides on Prebiotic Earth

The Center for Chemical Evolution’s recent article in Angewandte Chemie, “Ester-Mediated Amide Bond Formation Driven by Wet–Dry Cycles: A Possible Path to Polypeptides on the Prebiotic Earth,” has garnered a lot of press lately.

Boggs Upper-level Chemistry and Biochemistry Labs Renovated

Form follows function and so the Gilbert Hillhouse Boggs building second floor—originally housing research labs and now home to upper-level chemistry and biochemistry teaching labs—has been renovated (pictures, courtesy of HKS, Inc., below).

What are the limits of chemical detection? Here we show that single-molecular ion spectroscopy can be used to discover previously unmeasured vibrational transitions. The experiment starts with a chain of laser-cooled Ca+ ions that are only a few millikelvin above absolute zero. Hydrogen is leaked into the chamber until a single reaction to occur. We then probe the molecular ion transitions by two-photon dissociation, which results in a free hydrogen atom and a trapped Ca+. The bright atomic fluorescence of the Ca+ allowed us to observe the vibrational overtones by forming and destroying only a few hundred molecules.
